+Subject: [PATCH] python: return None if PY_IMPORT_STRING returns NULL
+
+PY_IMPORT_STRING might return NULL on python 3 if, ie, a string can't be
+encoded. We should check for this and return None, rather than returning
+NULL. Fixes a NULL pointer dereference when reporting an error with an
+invalid string.
